Vedclass · Answer

(B) For an ion to be coloured and paramagnetic,it must have unpaired electrons in its $d$-orbitals.$Cu^{2+}: [Ar] 3d^{9}$ (one unpaired $e^{-}$,coloured and paramagnetic).$Cr^{3+}: [Ar] 3d^{3}$ (three unpaired $e^{-}$,coloured and paramagnetic).$Sc^{+}: [Ar] 3d^{1} 4s^{1}$ (two unpaired $e^{-}$,coloured and paramagnetic).Therefore,the set containing $Cu^{2+}, Cr^{3+}, Sc^{+}$ consists of ions that are both coloured and paramagnetic.

The set having ions which are coloured and paramagnetic both is :
